Unsure if this is the correct forum for this question, but asking anyway.
Question 1
If a pro boxer fights an amateur (which would be considered an exhibition?) and even though there is no winner or losser, does their rating go up or down, or remains the same?
Question 2
If a pro boxer fights another pro boxer and wins, their rating would of course go up. But in the event it was found that the 'pro' boxer (who lost) was really an amatueur, then would that pro boxer rating drop? What would be done in a case like that?
Question 3
When pro boxers do exhibitons with each other, is their rating affected?
